鱼类鳞片、鳍、内脏等,都是宝贵的自然资源。由于综合开发利用不够,造成很大的浪费,甚至污染环境。加工利用鱼类废弃物,工艺简单,投资少,见效快,经济效益和社会效益都很显著。现简单介绍几种鱼类废弃物的加工项目,以供参考。1.利用鱼类废弃物生产鱼油和鱼粉鱼油主要用于提炼鱼肝油,也可代替矿物质油作皮革制剂,或用于制造治疗糖尿病、高血压等病的药物;鱼粉主要用作高蛋白质饲料。一般每吨鱼品加工下脚料,可生产鱼油30公斤,优质鱼粉200公斤以上。2.鱼皮制草鱼皮作为一种重要的皮革原料,正逐步被人们所重
Fish scales, fins, offal, etc., are valuable natural resources. Due to the comprehensive development and utilization is not enough, resulting in a great waste, or even pollute the environment. Processing and utilization of fish waste, process is simple, less investment, quick, economic and social benefits are significant. Is a brief introduction of several fish waste processing projects for reference. 1. The use of fish waste production of fish oil and fishmeal Fish oil is mainly used for the extraction of cod liver oil, mineral oil can also replace the leather preparation, or for the manufacture of drugs for the treatment of diabetes, hypertension and other diseases; fish meal is mainly used for high-protein feed. General processing of waste per ton of fish products, can produce 30 kilograms of fish oil, high-quality fish meal more than 200 kilograms. 2. Fish skin Grass skin as an important raw material of leather, is gradually being taken seriously
